SUPPORT FOR SHELVIN'G.

SPECIFICATION forming part of Letters Patent No. 443,355, dated December 23, 1890.

Application filed August 1, 1890- Serial No. 360,670. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH CAMPBELL, a citizen of the United States, and a resident of Middletown, Dauphin county, Pennsylvania, have invented certain Improvements in Supports for Shelving, of which the following is a specification.

The object of my invention is to provide a supporting device for shelving by which the various shelves may be adjusted to any desired height and which may be readily and cheaply constructed, as more fully set forth hereinafter.

In the accompanying drawings, Figure 1 is a perspective view of a series of shelves held in position by my improved support. Fig. 2 is a sectional plan of one of .the shelf-brackets. Fig. 3 is an elevation of the same, and Fig. 4 is a perspective view of the bracket and its clamping-plate detached from each other. i

The brackets 13 are supported upon a vertical bar or pipe A, and the end of each bracket is bifurcated, so that it partly embraces the bar, the bifurcated ends having suitablyshaped lugs adapted to the recessed clamping-plate C, which plate is cut away to permit the passage of the vertical bar or pipe A, as shown more clearly in Fig. 4. The ends of the bracket are held to the plate by bolts 12, passing through the lugs on the end of the bracket and the plate and clamping the bracket to the post A, as shown. The brackets may be adjusted to any position on the bar A by loosening the bolts 7), and may be held in that position by clamping the bracket and plate together around the post by tightening the bolts. The bracket is provided with suitable holes 0, through which screws may be passed for securing the shelves in place.

My improved shelving is especially adapted for display-racks for stores and windows, and may be made of ornamental character, as shown, for instance, in Fig. 1.

Having th us described myinvention, I claim and desire to secure by Letters Patent 1. The combination, in a support for adjustable shelving, of the vertical supportingbar, the bifurcated bracket embracing said bar, a clamp-plate recessed for the reception of lugs on the bifurcated ends of said bracket, and bolts for securing the ends of the bracket to the clamp-plate, substantially as specified.

2. The combination, in a support for adjustable shelving, of the vertical supportingbar, the bifurcated bracket embracing said bar, a clamp-plate recessed for the reception of lugs on the bifurcated ends of said bracket, bolts for securing the ends of the bracket to the clamp-plate, said clamp-plate being suitably shaped for the reception of the vertical supporting-bars, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOSEPH CAMPBELL. Witnesses:
